These are all the definitions for your codes.
It's hard to give an exact cause for these codes because of there are a number of different items that could cause these.
The first one could be caused by Incorrect camshaft timing,
VCT solenoid valve stuck open or continuous oil flow to piston chamber,
Camshaft advance mechanism binding, or faulty VCT unit,
The others are most likely bad sensors.
I wish I could be more help but it's difficult to trouble shoot this kind of problem without having the vehicle here in front of me.
Good luck

Check engine code 55 for 89 dodge caravan, obd11 code 55 for 89dodge caravan


55 is the "end of codes" code. If you only get this, then your vehicle has no stored codes.

1994 dodge truck codes 12 and 55


12-- Battery or computer recently disconnected. Check the connections or, wiring harness that is connected to the CPU. Make sure it is in good condition. Check the battery post cables for faults as well.

55 is end of codes - it's normal. Before you call your dealer or mechanic, consider that the blink-spacing is not always perfectly uniform, so if you see 23 23, it's probably just a single 55. (Codes are not repeated.)

your van has an obd1 setup with dodge all you should have to do is turn key to ign to off 5 times without starting vehicle and the check engine light will flash the code for example it will start off with a code 12 i believe saying the computer is functioning the check engine will flash 1 pause flash 2 pause and will repeat a total of three times just write down all the codes when it gets to code 55 it is done hope this is helpful

1990 dodge caravan starts then dies after 30 seconds.


cycle key, on,off,on,off,on & leave it on (not start) & count flashes from check engine light to see if getting any trouble codes. example: 2 flashes, pause, 2 more, is code 22. 3 flashes,pause & 3 more, is code 33, etc.. let us know what you get, if any. P.S. Code 55 - 5 flashes,pause 5 more, is end of message.

Finding truoble codes for 1994 suzuki sidekick


if you live in the states... just go to an autozone... they will scan the codes for free. you may also be able to retrieve the codes by turning the key off and on 3 times and counting the amount of times the check engine light flashes. almost like morse code... when you reach code 55 that's the end of the codes. this does not always work.
